added new modules from jochen
included 1D histo creation
Current ivfhistos.cpp and ivfselections.cpp modules with 4 hists classes, no base classes
Current ivfhistos.cpp and ivfselections.cpp modules with 4 hists classes, no base classes
Possible to make Z-Rho and Rho plots for both Geant and Decay processes but a bit messy
New branch with different histo classes, now deriving from two base classes
Rearranged tree analysis so no for each category/flag there is a specific selection
Implemented categorizations (ivfselections.cpp), some new histograms and a module that modifies the read-in vertex (e.g. to fix the 'PrimaryDecay' bug)
